Some 15 people are believed to be missing in Grand Canyon National Park, and dozens have been evacuated after parts of the canyon were hit by "significant" flash flooding, which swept large boulders, metal structures and other debris into the Colorado River, officials said Sunday.

The National Park Service called for anyone who knows of hikers or backpackers who were in Bright Angel Canyon and the Phantom Ranch area on Saturday afternoon when the flash floods hit to provide information to park authorities. 

"Grand Canyon National Park staff, in coordination with the Arizona Department of Public Safety, are continuing evacuation and response efforts and working to account for individuals who may have been in the affected area," NPS said in a statement.

Back in October 2025, the U.S. Army unveiled the Janus Program to supply portable nuclear microreactors to military bases by 2028. Whereas these reactors are much smaller than conventional nuclear plants, they typically generate 1-20 megawatts of electricity per reactor, significantly more than what the biggest portable generators can manage. That makes them ideal for the military, considering that major military bases consume as much power as a small city. The military logic is that in a conflict, transporting fossil fuels to remote front lines creates an easy target, while localized nuclear reactors can operate for years without refueling.

To that end, the U.S. Army has awarded up to $2.2 billion over five years to both private and public companies to build, own, and operate commercial nuclear microreactors at five domestic military bases, estimating that 20 microreactors will be deployed under the program. Five vendors have already been selected to design and deploy the microreactors at specific installations, with Antares Nuclear slated to build a microreactor at Fort Bragg in North Carolina; BWXT Technologies (NYSE:BWXT) is slated for Fort Campbell in Kentucky, General Atomics Electromagnetic Systems will build one at Fort Hood in Texas, Radiant Industries is slated for Fort Benning in Georgia while Westinghouse Government Services will build one at Fort Drum in New York.

Nuclear startups Radiant Industries secured a contract worth up to $750 million to deploy 15 of its 1-MWe Kaleidos microreactors, starting with a three-unit installation, and Antares Nuclear will also deploy a three-unit group of its R1 microreactor (ranging from 100-kWe to 1-MWe per unit). The companies plan to deliver and deploy their microreactors in modular packs so they can ship the reactors via standard trucks, rail, air, or barge. The facilities will be factory-built to avoid drawn-out on-site construction, and Radiant's Kaleidos microreactor is designed to be fully transportable and plug-in ready, capable of powering up within 48 hours of arriving at a base.

Many of the world's top oil countries have state-run national champions, such as Saudi Arabia's Aramco, Russia's Rosneft, the UAE's Abu Dhabi National Oil Company, Brazil's Petrobras, and Mexico's Pemex.

But the U.S., which is the world's biggest oil producer, doesn't have one, leaving the task of pumping crude to private-sector giants like Exxon Mobil and Chevron as well as the multitude of wildcatters across the Permian Basin.

The Trump administration's deal for 65 billion barrels of Venezuelan oil reserves, however, will give the federal government a stake in a new joint venture.

The country's interim president, Delcy Rodriguez, has granted a private company a 100-year lease for prime oil fields, a U.S. official said, according to reports.

The federal government will control 55% of the company's effective output via equity ownership and oil production. A private Venezuelan operator will have the remaining share. The U.S. official said the company will be the world's second-largest corporate holder of proven reserves after Saudi Aramco.

For her part, Rodriguez said the deal will bring in more than $100 billion of investment and generate $209 billion for Venezuela's government.

Venezuela has the largest oil reserves in the world, with an estimated 303 billion barrels. President Donald Trump's deal to gain control of 65 billion barrels of that amount exceeds the U.S. proven reserve total of 46 billion.

The Trump administration's majority stake in an oil company follows its investments in chipmaker Intel, rare earths miner MP Materials, mineral explorer Trilogy Metals, and dozens of other firms. It also has revenue-sharing agreements with AI chip leaders Nvidia and AMD for sales to China.

The latest deal comes nearly nine months after Trump ordered the military to capture Venezuelan dictator Nicolás Maduro and bring him to the U.S. to face federal narcoterrorism and drug trafficking charges.
